A protein mixture is aliquoted into several tubes, which are exposed in parallel to different temperatures and a thermostable protease. The remaining protein can be resolved on SDS-PAGE . Fast parallel proteolysis ( FASTpp ) is a method to determine the thermostability of proteins by measuring which fraction of protein resists rapid proteolytic ...
The resulting crosslinked proteins or protein complexes have been shown to exhibit increased stability towards thermal and chemical stress and a lower tendency towards aggregation. [ 1 ] [ 6 ] So far, the melting temperature of proteins was increased by up to 39°C in a single design step.
Thermostable proteins are often more useful than their non-thermostable counterparts, e.g., DNA polymerase in the polymerase chain reaction, [7] so protein engineering often includes adding mutations to increase thermal stability. Protein crystallization is more successful for proteins with a higher melting point [8] and adding buffer ...
Cycloheximide chases are also valuable for assessing how different mutations affect the stability of a protein. Experiments have been conducted in yeast and mammalian cells to determine the critical residues required for protein stability and how disease-associated mutations may be affecting protein half-lives within the cell.
In the less extensive technique of equilibrium unfolding, the fractions of folded and unfolded molecules (denoted as and , respectively) are measured as the solution conditions are gradually changed from those favoring the native state to those favoring the unfolded state, e.g., by adding a denaturant such as guanidinium hydrochloride or urea.

Gary J. Pielak (born July 17, 1955) is an American biological chemist who is known for developing quantitative techniques for measuring protein structure, stability, diffusion, and concentration in living cells, and under crowded conditions.
